Abstract (en)
The present invention relates to a non-aqueous electrolyte solution and a lithium secondary battery including the same, and, particularly, to a non-aqueous electrolyte solution, which includes a 1.2 M to 3.3 M lithium salt, a first organic solvent composed of ethylene carbonate, a second organic solvent excluding the ethylene carbonate, and an oligomer represented by Formula 1 as a first additive, wherein the first organic solvent is included in an amount of 0.1 wt% to 12 wt% based on a total weight of the non-aqueous electrolyte solution, and a lithium secondary battery including the same.
